An interesting mix of an actual historical figure and a fictional character, these two ghosts are an unlikely pair. Yes both were outlaws but Robin Hood was a more virtuous thief whereas Billy the Kid was a vicious gunfighter.
The Robin Hood damashii looks pretty much how you'd envision the ghost of the leader of the Merry Men of Sherwood Forest but Billy the Kid looks about as authentic as Marty McFly in Back to the Future III. It's a ridiculous approximation of a cowboy and I find it hilarious.
